Explanation:
Detailed explanation-1: -The oculomotor nerve emerges from the interpeduncular fossa as several rootlets that fuse to form a single trunk. The nerve then runs between the posterior cerebral artery and superior cerebellar artery, passing forward, downward, and laterally via the basal cistern (Adler and Milhorat, 2002).
Detailed explanation-2: -The lateral wall of the interpeduncular fossa bears a groove-the oculomotor sulcus-from which rootlets of the oculomotor nerve emerge from the substance of the brainstem and aggregate into a single fascicle.
